The inspector found that these three had been changed to TP's and have i

received the reviews and approvals required for TP's.

,

The inspector also reviewed an intersation letter, dated June 22, 1973, issued bv the plant superintendent to supervisors and test coordinators.

The letter emphasized that safety related test procedures must be reviewed and approved according to Sections 4.3 and 4.4 of the Administrative Policy Manual for Operational Quality Assurance of Nuclear Stations (APM/NS).

Review of Station Modifications The method for handling station modifications was reviewed with licensee representatives.

The method is currently being revised in answer to questions and comments from RO:II during a recent audit 1/ on Oconee 1.

During the interim period, a track sheet is being used to ensure all reviews and appropriate approvals are received.

Three modifications, currently being handled by the interim method, were selected by the inspector for review. The inspector found that each modification was receiving the reviews and approvals required by the procedure. There were no deficiences nor comments on the handling procedure.

4.

Review of Test Procedures and Test Results i

,

The following TP's and test results were reviewed by the inspector:

TP 203/4, "LPI System, ES Test" TP 240/4, " Component Cooling System Functional Test" TP 230/4, "RC Vent and Drain Functional Test" The inspector had no ccaments or questions on these test procedures or test results.

5.

Source Range Instrumentation Response During the initial approach to criticality at Oconee 1, the inverse multiplication plots were not effective in predicting the point the reactor would acheive criticality. To prevent this same situation from occurring at Oconee 2, changes are to be made that will increase the sensitivity of the source range detectors to multiplication neutrons.

~

The licensee has indicated that the planned changes will be to:

(a) Add moderntor around each of the source range detectors to increase their effective sensitivity. To preserve overlap between source and intermediate range channels, moderator will also be added around each intermediate range detector.

The prerequisites of the test procedures are signed or initialed, but they are not dated.

None of the procedures that have been rev1ewed show two sets of initials which would indicate reverification of the prerequisites.

It was noted that portions of some tests were performed at a given time and the remainder of the test performed after a significant amount of time had elapsed.

Further, the test coordinator's log does not, in most cases, contain entries indicating cocplecion of prerequisite verification.

Therefore, there is no way to determine when the prerequisites were verified and enere doesn't appear to be any existing evidence that any were ever reverified.

In cases where parts of a test are conducted at one time and other parts at another time, it may be desirable to reverify certain prerequisites or other test preparation.

Consideration should be given to the feasibility of identifying a time limit for which a verification is valid after a test interruption.

,

A licensee representative stated that an evaluation would be made to determine how best to improve this area of testing.

Station Quality Assurance (QA) Staff

~

The review made of the station quality assurance during this inspection indicates that an effective program is being conducted. A number of deficiencies were recorded in several areas as a result of QA audits.

i A brief discussion of audit reports inspected follows;

!

a.

Electrical Interlock and Bypass Log An audit of the electrical interlock and bypass log was made by i

the station QA staff on July 17, 1973.

Several deficiencies were noted and recorded in a QA audit report. All of the

,

,

'

tagged jumpers could not be accounted for and a number of open circuits were observed without tags.

A report containing the

findings of the audit was transmitted by memorandum to the plant superintendent.

On August 14, 1973, the plant superintendent

informed the operations supervisor of the QA audit findings by

,

'

memorandum and instructed him to take action at the earliest possible moment to correct the deficiencies.

The memorandum further instructed the operations supervisor to meet with the j

instrumentation and maintenance supervisors to determine how the

deficiencies were occurring. At the close of the inspection, the corrective action had not been completed._ This item will be carried as UN 73-11/2 and will be reviewed during a future inspection.

noted and reported to the plant superintendent.

A member of the QA staff indicated that a reaudit was planned for the near future.

c.

Red Tag Audit The review of a QA audit report of the red tag log dated August 2, 1973, indicated that five deficiencies had been noted and reported to the plant superintendent. A me=ber of the QA staff indicated that a reaudit was planned for the near future.

d.

Operator.and Shift Supervisor Log An audit report of the operator and shift supervisor logs covering the period from June 30, 1973, to August 14, 1973, was reviewed by the inspector.

The audit revealed no defic *.encies.

e.

Station PO Drawings An audit of station PO drawings was made on June'7, 11, and 12, 1973.

Several discrepancies were noted, primarily because the latest

-

revision of certain drawings were not in use or in the file. A reaudit was ccaducted on July 17, 18, and 19, 1973. Most of the deficiencies resulting from the June audit had been corrected, but several new ones were found.

f.

Field Changes On July 24 and 25, 1973, a member of the station QA staff made an inspection of certain Unit 2 field changes to verify correct wiring and retesting.

The field changes inspected vete:

FC-31 Rev. 2, FC-107, FC-109, FC-110, FC-lll, and FC-ll4.

No deficiencies were noted.

g.

Nuclear Fuel Records

,

An audit of nuclear fuel records was conducted on May 18, 1973.

All Unit 2 fuel records were found to be in order.

h.

Periodic Tests An audit was performed in August 1973 by the station QA staff of the operations group periodic tests.

One discrepancy was noted.

This was corrected within one week.

Chemistry Department Records An audit of the chemistry department boron sampling and calibration records was performed on August 29, 1973, by the station QA staff.

One discrepancy was noted. A reaudit is scheduled to be conducted within two weeks.

5.

Steam Production Department Quality Assurance Staff The inspector learned that this offsite quality assurance group had made its latest audit of the station proceedings during the week of August 20, 1973. The report of this audit was not available during this inspection.

The areas covered by the audit were nuclear materials, station modifications, tag out logs, emergency procedures, and the controlling procedure for hot functional testing.

Reports which resulted from earlier audits were reviewed.

The primary objective of this review was to determine whether meaningful audits are being conducted by the steam production department quality assurance staff, whether the frequency of the audits meet the requirecent of the Administrative Policy Manual for Operational Quality Assurance, and whether the audits are perfor=ed in accordance with written procedures.

No deficiencies were noted in these areas and the inspector concluded that the DPC offsite quality assurance program is

'

functioning in an adequate manner.
